| Abstract: | Five species of Eurasian birds displayed a range of mitochondrial DNA phylogeographic structures, including a single widespread
lineage (common sandpiper), two geographically unsorted and closely related lineages (long-tailed tit), three partially overlapping
closely related lineages (reed bunting), and two divergent geographically isolated lineages that rival species distinction
(red-breasted flycatcher and skylark). Only the red-breasted flycatcher and the skylark displayed congruent phylogeographic
structures. These five species represent different stages of diversification and speciation. There was little evidence that
natural selection had influenced mitochondrial NADH dehydrogenase subunit 2 (ND2) sequences. In several instances, population
growth was hypothesized, based on haplotype distributions within populations. |
